PS. In pondering these matters, it is useful to compartmentalise the idea of "address to which request is sent" (logically) from "the network and transport-layer destination (e.g. IP/port) used to reach the endpoint". In the case of NAT, they are not one and the same.
The RURI stays equal to the Contact remote target. The network destination itself can be whatever.
